Bridging Microswitch Adjustment

Bridging Microswitch:

The bridging microswitch is

located at the bottom of the

right (front) vertical arm. See

Photos A and B. An adjust-

ment screw is built into the

platform stop block.

The bridging microswitch will

be deactivated if the outboard

end of the platform contacts

the unloading surface before

the inboard end while the

DOWN switch is pressed.

The deactivated bridging mi-

croswitch interrupts power to

the DOWN switch circuit and

stops the down travel of the

platform (while allowing the

outer barrier to deploy).

Switch

Activation Lever

1. Position the platform at ﬂoor

level (or slightly below).

Ensure the platform is not

partially folded. From the

stowed position, press the

UNFOLD switch until the

pump stops running and the

platform comes to a full stop.

From below ﬂoor level, press

the UP switch until the pump

stops running and the platform

comes to a full stop.

2. Check both platform stop

blocks to ensure there is no

gap between the stop blocks

and the vertical arms. See

Photos B, C and D on page

7. A gap may indicate that the

platform is not fully unfolded or

the platform angle adjustment

bolts are not adjusted equally

on both sides.

3. Loosen the two jam nuts on

the bridging switch activation

screw (see Photo G). Tighten

the screw until the activation

lever is fully depressed. Verify

that there is no play in the

activation lever and tighten the

jam nuts.

4. Test lift for proper operation.

Bridging Microswitch Adjustment

Adjustment Guidelines:

Caution: This adjustment is

factory set and typically should

not require adjustment.

Before adjusting the bridging

microswitch:

• Adjust platform angle as

detailed on page 6.

• Adjust ﬂoor level position as

detailed on page 8.

• Ensure platform is in the fully

unfolded position.

• Ensure both stop blocks are

making full contact with vertical

arms (details on page 7).

Failure to follow these

guidelines will result in an

overtight adjustment that

will bend the adjustment

screw, break the bridging

switch and/or result in lift

operation failure.
